Return on your seeds

How far apart are you planting your kohl rabi? I grow 4 to a square foot, so six inches apart. They grow quite vertically and don't take up much horizontal space so are good for planting around the edges of beds. I love the crunch of kohl rabi in a salad, good for when radish and turnips aren't around.

I have about  8 plants 8" apart in a row covered in mesh to stop pests, when should they start bulbing? At the rate these are going it'll be winter before they do anything, they're a healthy 10" tall on stalks so far. I still don't think they're going to be a favourite,  I'm not keen on radish or turnip, so there's not a lot of hope for kohl rabi. Good to experiment though.

Maybe just under 2 months from seed to harvest? I've never timed it. Slower than turnips anyway.   You do get the odd one that doesn't form any bulb at all. Hybrid varieties are better than open-pollinated, they bulb quicker and don't go woody.
